The 150-tonne HD1500-8E0 is purpose-built for mining, quarrying and aggregates applications.
It delivers 1,580 gross horsepower (1180 kW) and features a Tier 4 final Komatsu SDA16V159E-3 engine to drive high levels of productivity. The redesigned cab, combined with a MacPherson strut-type and hydropneumatic suspension, is intended to give operators the smooth and comfortable ride they need for long shifts.
In addition to speed on grade, the HD1500-8E0 is equipped with hydraulic, wet multiple-disc brakes on all four corners. The continuously cooled, large-capacity brakes also act as a highly responsive retarder, providing operators with confidence at higher speeds when travelling downhill. Downhill descent can also be controlled by setting a desired travel speed with the automatic retard speed control (ARSC), which applies the brake retarder to maintain the desired setting and descend the road with confidence.
With a tight turning radius (11.2 m), Komatsu says that HD1500-8E0 operators can easily manoeuvre in and out of tight spaces when spotting to be loaded or positioning to dump. The MacPherson strut-type independent front suspension features an A-arm wheel-to-mainframe design for wide spacing and easy access to the engine bay.
Komatsu’s Traction Control System (KTCS) is designed to provide excellent control in loose or slippery haul-road conditions by monitoring the rear wheels for slippage and automatically applying pressure to the independent wheel-brake assemblies.
